Question about RCA D52W19 52" Rear Projection Television
If you've confirmed that the mute is not on, this is an indication that the audio board inside was gone bad. This is where the internal speaker was connected. The common faulty parts there is the sound output IC(mounted in heat sink) and some of the resistor. This IC fails because of constant heat exposure and also aging. Once replaced with new IC and some of the resistor, the sound will back to normal again.
Also, bad solder joints(dry/cold solder) is to consider in that board. This is hard to spot, I would advice you to find it in the brightest area or use a table lamp/portable lamp and magnifying glass.
If you don't have necessary tools and test instrument and can't do the job yourself, I would advice you to look for a qualified technician to troubleshoot the symptom.
Hope I helped you.
Have a nice day!
Thanks for using Fixya.
